EXTENSION WINDOW-SCREEN FRAME.

Specification of Letters Patent.

Patented Aug. 22, 1911.

Application filed June 6, 1910. Serial No. 565,233.

To all whom it may concern:

Be it known that I, GILBERT E. FERRY, a citizen of the United. States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Extension Window- Screen Frames, of which the following is a specification.

This invention relates to improvements in extension window screen frames, and has for its object, broadly, to provide screen frames of this class which may be economically constructed, will be reliable and convenient in use and of such form that they may be packed and shipped to advantage.

The invention has reference to a pair of connected screen frames which may be disposed vertically to obstruct a window opening and will be horizontally adjustable so that openings varying in widths may be screened; and includes the use of single metallic rods bent to a rectangular form as frames for the support of the borders of the wire cloth, cylindrical'clamping plates be ing mounted upon the frames as a holding means for securing the wire cloth upon the frame rods, compression bars being employed, the same to be disposed longitudinally of and mounted upon the ends of the screen frame to prevent sagging of the wire cloth and to close the passage way between the adjacent webs or sheets of wire cloth, these features tending to provide an article of few structural parts, as well asfeatures relating to con'veniencein use, durability, and attractiveness in appearance.

The invention consists of the novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the drawing, wherein,

Figure 1 is a vertical side view of a rectangular core or supporting frame which provides a seating for the wire cloth. Figs. 2 and 8 are sideviews of the two screen members of a pair, clips for sustaining the compression-bars being also shown. Fig. 4 is a vertical, side view of an extension window screen frame embodying my invention. Fig. 5 is a detail relating to Fig. 4, being an enlarged, broken away view between the irregular line a a and line 0 c of said figure, and showing the frame rods, wire-cloth, cylindrical clamping plates and clip in section. Fig. 6 is an enlarged, broken away sectional view between lines I) b and c c'of Fig. 4. Fig. 7 is a plan view of the extension window screen frame. Fig. 8 is a partly broken away, side view of the clip, and showing the socket for a mounting therein of the compression bar, an end portion of said bar also being shown. Fig. 9 is a view showing the opposite side of the clip to that shown in Fig. 8, a terminal part of the compression bar being added.

Referring now to the drawing for a more particular description, numeral 1 indicates an extension window screen frame comprising the slidably connected, rectangular frames 2 and 3. In the construction of frames 2 and 3 I employ a core-member or rectangular support, the same preferably consisting of a metallic rod 4 bent to the form mentioned and having adjacent terminals 5 midway between its ends 6. Heavy wire may be used to advantage for this purpose, and if desired the terminals may be united to form an integral structure.

After the wire cloth or gauze 7 has been mounted upon the rectangular core or frame-rod, its border encircling or partly inclosing said frame as shown in Fig. 5, the

slotted cylindrical jackets, sleeves, or trans versely curved longitudinal clamping-plates 8 are then secured upon that part of the wire gauze which bears upon the surface of frames 4.

Clamping-plates 8 may be constructed to advantage by use of sheet metal; they are cylindrical in form and may have lengths substantially equal to the horizontal or vertical parts of frame-members 2 or 3, and they provide firm holding means for the mounting of the wire cloth upon rods 4, the edges of longitudinal slots 9 of the cylindrical clamping-plates being disposed upon oppoe site sides of the screen. 1 7 Frame members 2, and 3 as thus described may be conveniently manufactured; no riveting or corner-pieces are required; terminals 5 of the frame-rods are inclosed or covered by the clamping-plates, and the frame-members present an attractive appearance.

I provide the compression-bar 10, its terminals being seated in holder-members or sockets ll'of clips 12, said clips having one of their ends closed, as indicated at 13. Members 2 and 3 may be disposed vertically adjacent to each other, with parts of their inner sides overlapping, and when one of clips 12 is mounted upon each of the upper and lower ends of these frame-members at the junction of their horizontal and one of their vertical sleeves 8 sockets 11 of the clips will be disposed adjacent to and in alinement with the vertical sleeve, and clips 12 will partly circumscribe and partly inclose the ends of the horizontal sleeves; and the partly closed ends 13 of the clips will prevent said clips from sliding inwardly of the horizontal sleeves.

Clips 12 and socket-members 13 are disposed transversely with reference to each other and, preferably, they are constructed' integral from a metallic sheet or plate, a curved engaging plate 14 being provided between the clip and socket and having a less length than the clip.

Members 2 and 3 are always employed in pairs to form an extension window screen frame, and when assembling these members, clips 12 are disposed upon the ends of said members as already described. Outwardly sliding movements of the clips will be prevented for the reason that they embrace the horizontal sleeves of the members; inwardly sliding movements will be prevented since, as above mentioned, the outer ends 13 of the clips are partly closed.

Engaging plates 14, when the clips are mounted, extend transversely from members 2 and 3, and they pass over and partly encircle the horizontal sleeve of the adjacent or opposite member, and compression bar 10 is adapted to have a bearing upon the outer surface of the wire cloth of said opposite member, or the member opposite to the one upon which the clip is mounted, whereby the two sheets of wire cloth of frame-members 2 and 3, adjacent to a bar 10, are compressed between said bar and a vertical sleeve; and the compression men tioned prevents sagging of the wire cloth, and prevents the formation of passage-ways therebetween, this feature being desired to prevent insects from passing between the two adjacent screens.

After the parts are assembled, members 2 and 3 may be adjusted to provide a screen frame of greater or lesser widths, the horizontal sleeves of one member sliding within the curved engaging-plates of the opposite member, and as is obvious, the compression bars of each member will be disposed parallel with andadjacent to one of its vertical sleeves, the wire cloth of the two frame members being disposed therebetween.

' Having fully described my invention, what I claim and desire to secure by Letters Patent is,-

1. In combination with the horizontal strips and one of the vertical strips of a rectangular screen frame; a compression bar mounted upon the horizontal strips and disposed in fixed relation parallel with, outwardly of and adjacent to said vertical frame; a second rectangular frame, said frames being disposed adjacent and slid ably mounted with reference to each other and each being provided with a screen; a compression bar mounted upon the upper and lower sides and disposed adjacent to one of the ends of each of said frames, the screens of each of said frames being disposed between said end of the adjacent screen frame and the compression bar of said adjacent screen frame.

3. In combination with the horizontal strips and one of the vertical strips of a rectangular screen frame; clips having longitudinal socket members and secured upon the horizontal strips, said socket members extending outwardly of, parallel with and adjacent to said vertical strip; a compression bar extending between and mounted in the socket members; a screen member mounted slidably within the clips of the rectangular screen frame with its screen disposed between the vertical strip of said rectangular screen frame and said compression bar.

4. In combination with the horizontal strips and one of the vertical strips of a rectangular screen frame; curved engagingplates each having a terminal holder-member, said plates being mounted upon and at one of the ends of the horizontal strips, said holder-members being disposed adjacent to the ends of said vertical strip; a compression bar extending between and mounted in said holder-members; a screen member mounted slidably within the curvedengag V ing-plates of the rectangular screen frame, its screen being disposed between the vertical strip of said rectangular screen frame and said compression bar.

5. A screen frame comprising a pair of slidably connected adjacent frame-members each consisting of a supporting-core formed.

frame-members of said pair and disposed outwardly of the wire gauze of the adjacent connected frame-1nember. 6. A screen, frame comprising a pairof slidably connected adjacent frame-members each consisting of an elongated supportingcore formed as connected horizontal and Vertical sections, wire gauze having border portions seated upon the sections 01": the supportingcore, a plurality of longitudinal jackets each formed with a longitudinal slot seated upon a border port-ion of the wire gauze inclosingly upon a section of the supporting-core and disposing the edges forming its longitudinal slot upon opposite sides of said Wire gauze; and a compressionbar mounted upon the jackets of the horizontal sections of one of said connected frame-members and disposed substantially parallel with and adjacent to a vertical section thereof, outwardly of the wire gauze of the adjacent slidably connected framemember of said pair.

In testimony whereof I have aflixed my signature in presence of two witnesses.
